The bright yellow solution was chilled in an ice bath, and 6.5 ml (0.078 mole) 12 N HCl was added. The yellow color disappeared and a white precipitate formed immediately. The solid was collected on a filter; rinsed with THF and air-dried to give 27.4 g white solid (99.3%), m.p. 190.5°-191.5° (dec.).
